Changes in foliar proline concentration of osmotically stressed barley.
The amino acid proline is accumulated in plant tissues in response to a variety of stresses. The existence of two routes for its biosynthesis is well documented. However, little is known about the contribution of each pathway to the accumulation of free proline under stress conditions. In the present study young barley plants were subjected to osmotic stress by treating their roots with 25% pol...
متن کاملSodium Distribution in Salt-stressed Citrus Rootstock Seedlings
Although citrus trees are considered relatively salt-sensitive, there are consistent differences in Na and Cl tolerance among different citrus rootstocks. We grew uniform seedlings of rough lemon (RL) and the more Na-tolerant Swingle citrumelo (SC) with and without 50 mM NaCl for 42 days. Salinity reduced leaf chlorophyll and plant transpiration rate (Ep) more in RL than SC. Confocal laser scan...
متن کاملThe use of laser light to enhance the uptake of foliar-applied substances into citrus (Citrus sinensis) leaves1
PREMISE OF THE STUDY Uptake of foliar-applied substances across the leaf cuticle is central to world food production as well as for physiological investigations into phloem structure and function. Yet, despite the presence of stomata, foliar application as a delivery system can be extremely inefficient due to the low permeability of leaf surfaces to polar compounds. METHODS Using laser light ...
متن کاملInternal Water Status of Kinetin-treated, Salt-stressed Plants.
Stomatal resistances and turgor pressures were measured during a 12-day period on leaves of bean (Phaseolus vulgaris L. cv. Contender) which were treated with kinetin, were salinized or were treated with kinetin and salinized. Stomatal resistances were highest in salt-stressed plants, and progressively lower in salt-stressed and kinetin-treated plants, control plants, and kinetin-treated plants...
متن کاملPhospholipid Signaling Responses in Salt-Stressed Rice Leaves
Salinity is one of the major environmental factors limiting growth and productivity of rice plants. In this study, the effect of salt stress on phospholipid signaling responses in rice leaves was investigated. Leaf cuts were radiolabeled with 32P-orthophosphate and the lipids extracted and analyzed by thin-layer chromatography, autoradiography and phosphoimaging. Phospholipids were identified b...
